"To ALL WECMl 1T MAY CCNCEBN:

Be it known that VI, CHISTAN REINHART, of the city and'eounty of New Haven, in the vState of Connectieut, have invented certainnew and useful Improvements -in Eseapements fol-.Marine and other Clocks and .flime-Pieces; and the following is la, full, clear, and exact description ofv the same, reference being hadV to the accompanying drawings, making a part of ,this specification, which- Figure 1 represents a top view offthe balance-wheel, forked lever, pin-lever, and double-toothed crownwheel in their relative positions.

' Figure 2 shows a. sideelevation; with a view of theIescapcment-shaft and pallets, and frame for hanging and adjusting the same to the crown-wheel.

lignre4 3 shows afdetached view of the same in perspective,'enlarged. Figure 4 is an enlarged view. of the lever, pin-lever, and broken-oli` section of the crown-wheel.'

Figure 5 is thedouble-toothedwheel and check-plateA or top pallets. i Figure 6 shows an edge view of the same parts as shown in tig, 4,

Figure 7 is a side view of iig. 5. p f Figures and 9 show the escapement-.collets. A To enable others to make and use my invention,I will describe it more ful1y,`referringto'the drawings, and to the letters marked thereon. i The object of my invention is to get a durable and eiiicient escapem'ent for marine clocks and other timepieces; .and it consists in theconstruction ofvthe double-toothed' crown-wheel, the Acollet orl plate-verge, and stop-pallet, on a vertical shaft, the short forked-lever, and pin-arm, as arranged and combined with a balancewlieel,hair spring, and regulator. A

I make the escapement or crewn-whecl A double, it having two rims; on which the teeth a a. a, being very sharp pointld, incline to each face, so as to leave a space, b, between the points a a a. The collet B, which forms the vege proper' of this escapement, is made of steel, and fitted on to a vertical shaft, C, to which the forked lever D is secured, so ae vto oscillate the required distance to allow the points of thctecth a a a to escape alternately right and left through the inclined spaces or notches, e e, in the collet B.

On the `vertical shaft C, a short distance above the collet or verge B, I place the stop-plate E, which is also made of steel; and is provided with one open space,f, through which the teeth a a of the crown-wheel A escape as the lever D vibrates. The pallets z' on each side of the opening f in the stop-plate or collet E, check the movement of the crown-wheel. At the same time, the motion of the lever being reversed, the inclines j 3,011 the co1let-verge B, give momentum to the lever, so that the fork dd, acting on the pin t, in the arm/k, which is connected with the shaft G, on which the balance-wheel H is hung, gives a lively vibratoy movement to the balance-wheel H and shaft, on which the pin-lever k issecured, so that they nearlydeseribea circle at each beat of the escapement, thevdistance the forked lever is allowed to move being controlled by the width of the opening-en, in the arm of the lever D, and the pin or stud n for thelever to strike against.

The balance-wheel, shaft, lever, and verge-collets, with the shaft on which they are placed, are all arranged and,supported'in a frame, F, independent of the plates I I, in which the clock-'movement is arranged, so that it can be placed in any positionto come in Contact with the double-toothed crown-wheel that it may be desirable to have it placed in, so that the movement for marine clocks, or other time-pieces, can be arranged in the most compact manner, andoccupy but very little space.

l My improved escapementl may be applied tol clocks or time-pieces of' any form croi' any dimensions, and for the accuracy of its performance and certainty'of action cannot be excelled by any escapement that has yet come to my knowledge. v v

The advantages of my improvement are, that the clock measures time with greater accuracy than those with the ordinary rack or detached-lever eseapements, it having a greater forceof movement, will run with much less power of springgthan other-eight, fourteen, er'thirty-day clocks, and consequently will be moredurable, less liable to wear in its boxes, and is much easier wound up,

It will readily be seen that the advantages above enumerated are no small desideratum in u marine clock or other time-piece, and it is contidently believed that the escapement-movernents,I constructed as above described, (and jewelled,) as I propose to make them. will last, to keep correct time, a century or more, or as long as the clock-movement is kept together. Y

Havingthus fully described my invention, what I claim s new, and desire to secure by Letters Patent, is

1. The double-tooth crown-wheel A, as constructed, in combination with the vergecolletB and stop-collet E, operating substantially asand for the purposes herein specied.

2. The verge-collet B, stop-plate'E, as constructed and arranged, in combination with the forked lever \D, pin L, arm la, and balance-wheel H, as set-forth.

3. The forked lever D, with its open space mi stop pin or stud n, when the lever is halancedon the vergeshaft C, so as to distance the motion of the collet B and stop-plate Epto allow the points d a to 'escape through the incline openings e e and opening f, as herein described.

In testimony whereof, I hereunto subscribe my name in the presence of-L- CHRISTIAN REINHART.
